Add your phone number via SMS text message to a short code

Note: If your mobile operator is one of our supported carriers, you can use a short code with your Twitter account to post Tweets, receive notifications and enroll in security features like login verification. Here's how:

Text your username to the same number. Do not use the @ symbol or quotation marks. Send your username ONLY, for example: larrybird

Next, text your password. This is case sensitive, so be sure you are sending your password correctly.

You're ready to go! Now you can post Tweets, receive notifications about your account, and enroll in security features like login verification.

Add your phone number via SMS text message to a long code

Note: If your country and carrier are not listed as having a short code, it may be possible for you to post a Tweet using any of our Twitter long codes.

If you have to use a long code, note that it is one-way only. You will not be able to receive Tweets or other Twitter notifications to your phone through this channel, and you may be charged international message rates when using these codes. For these reasons, we do not recommend features such as login verification for long code users, as the experience may be less than optimal.

Begin by sending two separate text messages to the long code with the word STOP.

Wait two to three minutes before proceeding.

Send a text message to the long code with the word START.

Wait two to three minutes before proceeding.

Text YES to the Twitter long code.

Wait two to three minutes before proceeding.

Text your username to the same number. Do not use the @ symbol or quotation marks. Send your username ONLY, for example: larrybird

Wait two to three minutes before proceeding.

Text your password. This is case sensitive, so be sure you are sending your password correctly.

You’re ready to go!

Note: Make sure to wait a few minutes between each step to make sure Twitter is receiving your messages correctly.

To test if you have correctly added your phone, send a test Tweet to your long code number (just like sending a normal text message). Then, log in to www.twitter.com via the web to make sure your Tweet shows up on your Twitter profile. If it does, you have correctly added your phone. Once again, you will not be able to receive any texts back from a long code.

Adding your phone number to multiple accounts

You can have the same phone number associated with up to 10 Twitter accounts. It’s important to note that only the account most recently linked to this phone number can receive SMS notifications (for account activity like Direct Messages, new followers, Retweets, etc.) or perform SMS commands (such as sending (D [username] + message) for DM or RETWEET [username] for Retweets). You can adjust these notifications in your Text notifications settings. Find instructions for adjusting your SMS notification settings.

You will not be able to edit text notifications settings for any other accounts you have previously associated with your phone number. If you attempt to edit your settings on an account that isn’t your primary account, you’ll receive a message letting you know that the account cannot get these notifications because it shares a phone number with another account.

Note: If your phone number is linked to multiple accounts, you will not be able to choose which account can edit the SMS notification settings. Only the most recently linked account has the ability to change these settings. Each account that has your phone number associated with it will still receive SMS text messages for password reset requests or security features like login verification.
